Inventor: GERHARD KUNZE
IPC: F25B33/00
Filed: 2001-03-20
Abstract: The invention relates to an absorption refrigeration machine using the Platen-Munters system and comprising a generator (7) for evaporating a refrigerant in a solvent, a solvent separator (2) in which the solvent is separated from the refrigerant; a condenser (3) for liquefying the refrigerant; an evaporator (4) in which the refrigerant is evaporated using a dry gas while beeing cooled; possibly a first gas heat exchanger (6); and an absorber (5) in which the evaporated refrigerant is added to the depleted mixture of refrigerant and solvent which is then again evaporated in the generator (7). The output of the evaporator (4) or the output of the first gas heat exchanger (6) which is possibly positioned downstream of the evaporator (4) and the output of the generator (7) discharge into a bypass (8) connected to the absorber (5). The mixture of evaporated refrigerant and dry gas which arrives from the evaporator (4) via the first gas heat exchanger (6) is transferred to the generator output and from there into the bypass (8), where the gas mixture is brought into contact with the hot, partly, degassed solution coming from the generator (7) and withdraws further refrigerant from same.

Title: Power conversion apparatus
Inventor: YURA MOTOSUMI
IPC: H02M7/797
Filed: 1995-01-04
Abstract: PURPOSE: To use regenerative current with less distortion for control by continuously varying on/off duty factor according to their magnitude to PWM-control the phase of transistors other than one that is kept on. CONSTITUTION: The magnitude of phase voltage is determined through a comparing circuit 13, and one cycle of the supply voltage is divided into six sections. The current section is judged, and the resultant section data is transmitted to a Tr selecting circuit 14. The start and stop of regeneration, or the start and stop of the output of a PWM circuit 4 is judged. The Tr selecting circuit 14 selects transistors Tr1-Tr6 to be turned on/off according to the judged section data, and the PWM circuit 4 outputs control signals to turn on/off the Tr's. In the section 2, the Tr1 where phase voltage is the highest of the three phases and the largest current is passed, is kept on. The Tr4 is kept on at the start of the section 2, but its on/off duty factor is gradually reduced with the lapse of time. Contrarily, the Tr6 is kept off at the start of the section 2, but its on/off duty is gradually increased with the lapse of time.

Title: Improved exhaust noise suppressor for reaction engines
IPC: B64F1/26
Filed: 1961-01-03
Abstract: 920,404. Exhaust silencers. CURTISS-WRIGHT CORPORATION Jan. 3, 1961 [Oct. 27, 1960], No. 258/61. Class 7(2) An exhaust silencer for an engine having an exnaust nozzle 21, Fig. 3, comprises a cylindrical entrance section 12 co-axially surrounding the nozzle, a three - dimensional labyrinthine cribwork diffusing screen 16 positioned in the entrance section, a larger cylindrical expansion chamber 13 having inner and outer walls, 19, 20, a grid 17 positioned within the expansion chamber and a discharge stack 14 angularly disposed to the expansion chamber. The silencer is mounted on a wheeled carriage, provided at its ends with jacks, and is aligned with the engine nozzle 21. Exhaust gas from nozzle 21 entrains air through the converging throat at a speed of Mach 1 or higher, to cool the gases and prevent noise radiation upstream. After passing grid 16 in labyrinthine paths, where it may be cooled (see below), it expands in section 13, grid 17 being adjustably positioned to form a second diffuser, and thence into stack 14 where noise is further absorbed in resonant chamber- 18. Sections 12, 13 and stack 14 have outer walls of mild steel and inner walls of foraminous stainless steel, the spaces 19 being filled with glass or asbestos fibre. The screen 16 has ranks of rungs 36a, 36b, 36c, 36d, Fig. 4 which may be either carbon steel rods or stainless steel tubes arranged so that rungs do not occlude parallel rungs in other ranks. In a modification a diffuser 16a Fig. 5, which is radially non-symmetrical is mounted by reds 58 secured to brackets on the entrance section wall. Grid 17 is formed of welded criss-cross metal rods attached to a circular metal hoop. Cooling.

Abstract: 1515081 Thermal regenerators A RUTSHTEIN and N STAROSELSKY 6 Jan 1976 [9 Jan 1975] 280/76 Heading F4K In a method of operating a group of at least three hot blast stoves 403-406 associated with a blast furnace, the hot compressed air remaining in one of the stoves after it has been cooled and disconnected from both the common cold air manifold 402 and common hot air manifold 411 is fed through an auxiliary common hot air manifold 412 inter-connecting only the stoves in order to burn the fuel in one of the stoves being heated which fuel is supplied through a manifold 449. A cold air supply independent of that supplied by a turbo-blower 401 to the main manifold 402 is provided by a compressor 426, compressed air accummulator 425 and auxiliary manifold 450 to a stove ready to go on-wind and which has had its pressure equalized with that of a cooled and disconnected stove by filling it via the auxiliary manifold 412 with hot compressed air therefrom in order to utilize the thermal energy of the air remaining therein. The sequence of operations for switching the stoves 403, 406 is effected automatically by a programme logical device 436 receiving signals defining the positions of cut-off or discharge valves 407-410, 413-416, 421-424 and 432-435, throttling means 417-420 and 445-448 and also the signals of transducers 437-440 for measuring differences of pressure between that in manifold 402 and each of the stoves and transducers 441-444 measuring pressure differences in the auxiliary manifold 412 and stoves 403 to 406. The fluctuations in pressure and volume of the hot air supplied to the furnace on change-over of the stoves whether operated in alternation or displaced in phase are thereby stated to be reduced.

Title: Circuit including a photoresponsive insulated gate field effect transistor
IPC: H01L29/00
Filed: 1970-01-06
Abstract: 1276463 Photoresponsive semi-conductors INTERNATIONAL BUSINESS MACHINES CORP 6 Jan 1970 [15 Jan 1969] 571/70 Heading H1K A photoresponsive insulated gate FET comprises a P-type substrate 10 containing diffused N-type regions 12, 14 defining PN junctions 16, 18; the substrate being covered by SiO 2  layer 20. Ohmic contacts 22, 24 are made to the PN junctions which are bridged by a gate 26 overlying the SiO 2  layer. A source-drain potential source Vd is connected positively to source contact 24 and negatively to drain contact 22, while gate 26 is connected to region 12 over ohmic contact 28. Light incident on the source penetrates through regions 12 and 14 to the junctioning 16 and 18, while an external voltage source is connected positively to 22 over resistance 32 and negatively to 10 over resistance R S ; the voltage across the substrate biasing the FET "off" by substrate potential V SUB . On incidence of light from 30, the reverse bias current increases to develop a further voltage drop across R SUB  formed by the geometry of the source junction, and it is shown by mathematics that current gain bandwidth is given by where g<SP>s</SP>m = substrate transconductance C = C(O)A W = channel width A = source junction area L = source-drain distance Á = surface mobility V SUB  = substrate potential Vd = source/drain potential and is inversely proportional to transistor size i.e.(W/A #1/W). The source junction area may be square of side W and channel length L; the source drain and series resistance R S  being formed by a shallow square diffusion permitting incident light to penetrate the surface through an anti-reflection coating (Fig. 2, not shown). In an application (Fig. 3) the phototransistor comprises gate 36 receiving signals to control current between source 38 and drain 40, and is biased "off" by V 0  over series resistor R S . A load FET 42 is connected between transistor 36 and B+ source, while FET's 44, 46 constitute an inverter driven by the combination of 36 and 42. The net current gain is given by g<SP>8</SP>m g<SP>g</SP>m R s <SP>2</SP>, where gm is transconductance of driven circuit, R SUB  is determined by source junction design, and adjustment of R S  varies speed of response and resistivity, so that the change in current between source and drain exceeds the change in reverse bias current. The circuit and an array of circuits may be integrated and the gate electrode may be utilized to initiate logical functions.
